Decoding Human Muscle Names
Stop memorizing muscle names as arbitrary Latin jargon. Discover the simple visual code of shapes, sizes, and attachment points that makes anatomical names instantly make sense.
Like Duolingo, but for Decoding Human Muscle Names. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Cracking the Naming Code and Mapping the Trunk and Limbs. It starts from scratch.

Key ideas in Decoding Human Muscle Names
- Muscle names are functional descriptions of what they do, where they sit, or what bones they connect to
- Breaking a muscle name into parts reveals its action (flexor) and location/anchors (wrist, radius bone)
- Size labels exist in contrasting pairs to distinguish neighboring muscles in the same region
- Maximus/minimus refers to total bulk or volume (like gluteus maximus)
- Major/minor usually distinguishes larger and smaller flat surface areas (like pectoralis major)
- Deltoid is named after the triangular Greek letter delta
- Early anatomists used simple geometric silhouettes (triangles, trapezoids) to label major muscle contours
- The prefix tri- means three and -ceps stems from the word for head
- Biceps has two heads, triceps has three, and quadriceps has four distinct upper tendons anchoring to bone
- Rectus means straight or parallel to the body's midline
- Transverse means running horizontally across from side to side
- Oblique means running at an angle or diagonal
- Pectoralis major is the broad, superficial fan across the front of the chest that powers pushing movements
- Pectoralis minor lies deeper and hidden underneath pectoralis major
- Pectus is the root meaning chest or breast
- Latissimus dorsi spans a massive triangular sheet across the lower and mid-back

Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Decoding Human Muscle Names the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
When you see a muscle named 'flexor carpi radialis,' what happens if you break the name into parts?
